Battle.net now offers a list of hotfixes for Diablo III dated today (thanks Chris). The new server-side update addresses some bugs and increases the rate of high-end item drops for Acts III and IV in Hell difficulty and the entirety of Inferno difficulty. Here are the new approximate drop rates:

Items

The drop rates for high-end items (items level 61-63) have been increased for Acts III and IV of Hell difficulty and Acts I – IV of Inferno difficulty:

The new approximate drop rates are as follows:

Hell – Act III and Act IV

iLvl 61: 9% to 13.9%

iLvl 62: 1.9% to 3.45%

iLvl 63: 0% (no change)

Inferno – Act I

iLvl 61: 17.7% to 23.9%

iLvl 62: 7.9% to 12.6%

iLvl 63: 2.0% to 4.8%

Inferno – Act II

iLvl 61: 18.6% to 23.3%

iLvl 62: 12.4% to 18.6%

iLvl 63: 4.1% to 9.3%

Inferno – Act III and Act IV

iLvl 61: 24.1% to 27.1%

iLvl 62: 16.1% to 21.7%

iLvl 63: 8.0% to 16.3%

Bosses

Bosses are now guaranteed to drop at least 1 Rare item for players with 4 stacks of Nephalem Valor and at least 2 Rare items for players with 5 stacks of Nephalem Valor

I love how 2 million LVL 60 Diablo3 players are jumping up and down for joy over this hotfix, but little do they know that the quality of those items are nerfed down, and will still require AH/RMAH to get the best items for play that Blizzard themselves , generate in there.
